Technical Field

the invention relates to the technical field of manufacturing of snow sweeper accessories, in particular to a device for limiting the up-and-down stroke of a snow removing roller brush.

Background

The snow sweeper is an indispensable special vehicle for preventing accumulated snow, snow disaster rescue and the like when cleaning and snowing roads in winter in the north. At present, most of main snow removing components, namely the snow removing rolling brush, are arranged in the front of an automobile body, namely the rolling brush is arranged on a front baffle frame of the automobile body through a rolling brush long pipe and a rolling brush mounting frame, the rolling brush mounting frame and the rolling brush long pipe use a sleeve connection, an oil cylinder for driving the rolling brush mounting frame to move up and down around the rolling brush long pipe is arranged between the rolling brush long pipe of the rolling brush and the rolling brush mounting frame, and brush seedlings are arranged at two ends of the lower part of the rolling brush through the mounting frame. When the rolling brush is used for snow removal, the rolling brush needs to be pressed down through the oil cylinder, and the brush seedlings of the rolling brush are in contact with the ground so as to brush accumulated snow. If the pressing amount of the rolling brush is too large, brush seedlings under the rolling brush are seriously deformed, the working pressure of the motor is increased, and the brush seedlings or the motor are damaged; if the rolling brush is pressed down too little, the pressure of the brush seedlings on accumulated snow on the ground is insufficient, and the snow can not be removed, so that the stroke range of the rolling brush which is pressed down needs to be well controlled.

Disclosure of Invention

The invention aims to solve the problem that equipment is damaged or snow can not be removed due to poor control of the downward pressing stroke of a snow removing rolling brush of an existing snow remover.

In order to solve the problems, the technical scheme of the invention is as follows: the adjustable rolling brush downward-pressing limiting device comprises a rolling brush, wherein the rolling brush is arranged on a front baffle frame of an automobile body through a rolling brush long pipe and a rolling brush mounting frame, the rolling brush mounting frame is connected with the rolling brush long pipe through a sleeve, an oil cylinder for driving the rolling brush mounting frame to rotate around the rolling brush long pipe to enable the rolling brush to move up and down is arranged between the rolling brush long pipe and the rolling brush mounting frame, brush seedlings are respectively arranged at two ends of the lower part of the rolling brush, an upper end limiting seat is arranged by taking a concentric rolling brush rotating shaft in the rolling brush long pipe as a rotating center, a lower end limiting seat of a seat limiting plane is arranged on the rolling brush mounting frame around the rolling brush long pipe, a limiting rod is arranged on the upper end limiting seat in an inclined mode and is fastened by a limiting screw, and; when the stroke of the rolling brush is limited, the rod limiting plane and the seat limiting plane form an included angle with the axial center line of the long tube of the rolling brush as a base point; when the travel of the rolling brush is limited, the rod limiting plane and the seat limiting plane are attached to form a plane.

In the above technical solution, a more specific solution may be: the limiting rod is provided with a threaded section and penetrates through the upper end limiting seat, and the threaded section is connected with the upper end limiting seat in a matched mode.

Further: the limiting screw is fixed at the threaded section of the limiting rod and is matched and fastened with the upper end limiting seat.

Further: at least two limiting screws are respectively fastened above and below the threaded section on the upper end limiting seat.

Further: two limiting screws are respectively fastened above and below the threaded section on the upper end limiting seat.

Due to the adoption of the technical scheme, compared with the prior art, the invention has the following beneficial effects:

the adjustable rolling brush downward-pressing limiting device is characterized in that a rolling brush long pipe is taken as a center (the axial center line of the rolling brush long pipe is taken as a rotation base point, A point), an upper limiting seat of an upper belt rod limiting plane and a lower limiting seat of a belt seat limiting plane which can rotate are respectively arranged, when an oil cylinder extends, a rolling brush mounting frame is driven to rotate around the rolling brush long pipe to enable a rolling brush to move downwards, and when the rod limiting plane (surface B) and the seat limiting plane (surface C) are jointed into a plane, the oil cylinder stops acting, namely the optimal rolling brush descending stroke is achieved, the phenomenon that brush seedlings are too low in pressure and deform is avoided, and snow removal power is optimal; the limiting rod is provided with a threaded section and is connected with the upper limiting seat through threads, so that the connection is convenient, the limiting rod can be adjusted up and down relative to the upper limiting seat within a certain range, and the maximum value of the whole rolling brush stroke can be adjusted within a certain range; not less than two limit screws are fastened above and below the upper limit seat, so that the phenomenon that when a rod limit plane (B surface) and a seat limit plane (C surface) are attached to form a plane by using a single limit screw is avoided except that the fastening is not good, the oil cylinder can continue to act to enable the seat limit plane (C surface) to jack up the limit rod for one section due to the fact that the position of the limit rod below the upper limit seat is not limited and fastened, and the limit fails is avoided.
